Speaking as a Meteorologist, Fly Boy Knight, is 100 % correct.
I did need to learn all that stuff in college, and actually needed to do it on the job, back then the NWS only came out with the surface analysis once every 6 hours.
There is an 'art' to it, isobars generally run parallel to the winds with lower pressure to ones left with the winds coming to your back, in the Northern hemisphere. Sharp kinks indicate frontal boundaries, squall lines, and troughs, this is where the 'art' comes into play, the analysis, as to where the fronts are.
When I taught aviation weather at Dowling College, I made sure all my students did it, just so then would have an understanding as to what the charts meant.
